ya, the head had alot of corrostion on it when i got it but i got most of it off, looked like some was holding the valves open a bit but i cleaned it out and it wasnt doing it anymore, i could do that though and thought about it but was trying to get around that, but i spose i gotta right, well ill do that this weekend shouldnt take long, but ya i thought it odd to have compression in the #3 and not the number 2
